Contemplating a tummy tuck...

Hello everyone! After the birth of my first child, I went on a serious weight loss journey. I am proud to say that I was able to lose over 70lbs and keep it off the last two years. Now I am left with lots of extra skin on my stomach that all the exercises in the world can't change. Has anyone ever had one done? What was your experience? I am not new to surgery as I had a breast reduction back in 2008, but the thought still makes me nervous. I feel like I have worked so hard and finally getting this extra skin off will be so freeing. Here are some pics to show you what I am talking about.
